Every underground mine site needs a big truck with big pulling power. And that's exactly what you get with every Ram Heavy Duty pickup equipped with a specially calibrated Cummins 175-hp Turbo Diesel. These trucks out-perform every other pickup at the mine site with their combination of low emission engine, maneuverability in tight, confined spaces and high payload. No wonder it's the number one choice of underground coal mine operators in the U.S.
